July 11 network change will affect some off-campus Internet users
May 23, 2006 :: Mike Palladino, Information Systems & Computing, Associate Vice-President
For security reasons, Penn needs to restrict access to its Domain Name
System (DNS) servers to on-campus users. Internet Service Providers (ISPs),
including Penn and commercial ISPs such as Verizon, use DNS to translate
alphabetic computer names into their corresponding numerical addresses,
eg. www.google.com into 18.104.22.168, etc. Without DNS services, users
would have to remember and use these numerical sequences.
Beginning July 11, Penn’s DNS service will stop accepting name
translation requests from off-campus computers. On-campus Internet users
will not be affected by this change. Nor will most off-campus users be
affected; they are likely using their ISP’s DNS service already.
However, any off-campus users who have manually configured their computer
with Penn’s DNS servers will need to alter their configuration
to use DNS servers operated by their ISP before July 11.
